Choosing shear blade profiles

admin — Mon, 12 Jul 2010 11:58:34 -0700

In shear slitting, blade profile is one of the most frequently asked questions. While slit-edge quality is the result of many factors, blade profile is one of the factors most frequently changed in an attempt to improve slit quality. Often, a profile change does not yield the expected results because the shearing mechanism itself is not well understood.

Razor Slitting; Four Factors to Consider

admin — Fri, 09 Jul 2010 16:43:13 -0700

The three most common methods of slitting flexible web materials are shear, crush (score), and razor. Of these three, razor has the lowest installed cost, being the simplest and cheapest method. It can be easily adapted to almost any machine, in almost any location. It is potentially the cleanest method of slitting, assuming the appropriate materials are being slit.

Score slitting; Five factors to consider

admin — Mon, 12 Jul 2010 11:46:16 -0700

Score slitting, often referred to as “crush” slitting in international markets, is a common method of separating the web. Basically, a hardened steel disk is pressed against a rotating, hardened steel cylinder, creating a crushing nip into which the material is directed. The resultant nip force exceeds the ultimate yield of the material, and the material is severed along the nip line.

The role of the knifeholder in shear slitting

admin — Tue, 06 Jan 2009 09:23:54 -0800

Gone are the days when a shear-slitting knifeholder was a primitive, cast-iron contraption that required a pocketful of wrenches every time a pattern change was made. It had to have the durability of an anvil because repositioning involved a lot of pounding with a hammer. Lost time, lost product and accidents were a fact of life. This, of course, is no longer acceptable.

Tips for Slitting Aluminum Foil

There are several methods of slitting aluminum foil, including shear, razor and crush (score) slitting. This discussion focuses on the shear slitting method, since it is capable of slitting under a far wider range of calipers, tempers, and speeds than razor or crush methods.
